In this review, we investigated the diagnostic value of the sonographic “whirlpool sign” in identifying ovarian torsion. This was done by performing a search in PubMed, Scopus, Embase, Web of Science, CINAHL, and Google scholar. Additional search for the grey literature was made in EThOS.bl.uk , explore.bl.uk , opengrey.eu, greylit.org , and clinicaltrials.org . A total of eight studies were included in this meta‐analysis. Sensitivity and specificity of whirlpool sign were extracted from the studies and computed into the Metadisc statistical software for pooled analysis. The whirlpool sign showed a high sensitivity and specificity for the diagnosis of ovarian torsion.
